IMPROVEMENT IN APPARATUS FOR THE MANUFACTURE OF OIL-CLOTH.

Specification forming part of Letters Patent No. 153,650, dated July 28, 1874; application filed i July 24,' 1m.

CASE C.

To all whom it may concern.'

Be it known that I, AMOS WILDER, of Augusta, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Machine for Marking, Ribbing, or Scoring the Brush-Coat of Oil-Cloth, ofl which the following is a specification:

My invention relates to a new and improved apparatus for scoring, marking, or ribbing the brush-coat of oil-cloth, for the purpose of ornamenting and finishing the same; and it consists of a roller of peculiar construction mounted in the lower end of a frame arranged in ways or grooves between two upright standards secured to a bed or base, and firmly joined at their tops by means of a cross-beam, said frame being capable of a slight vertical movement in the ways or grooves, and connected to a screw passing through the cross beam, by means of which it can be raised or lowered, said roller working in combination with a roller below, the journals of which have bearings in the upright standards, and which is capable of a movement in a longitudinal direction, as will be fully hereinafter set forth.

In the drawings, Figure l represents a front view of my improved apparatus for scoring, marking, or ribbing the brush-coat of oil-cloth Fig. 2, a transverse section of the same.

A A represent the two vertical standards lirmly secured to a base or bed, B, and braced at the top by means of a cross-beam, C, as shown. These standards are provided with ways or grooves D D, into which is set a vertical groove, E, carrying the scoring, marking, or ribbing roller F. Said roller is mounted upon a shaft, G, having bearings in opposite sides of the frame E, one end of said shaft passing through the frame and a slot in one of the upright standards, and being provided with a driving pulley, H, by means of which the roller may be rotated. The roller may be made of any desired length, generally from about six to thirteen, and is grooved around its periphery, so as to score, mark, or rib the brush-coat of the oil-cloth when the same is passed between it and the roller below. These grooves may be made to run parallel to each other around the roller, at suitable distances apart; but I prefer, and regard it as an important feature of the invention, to form them spirally around the roller, or in the shape ofr a screw-thread extending around said roller from end to end. In this mannerv the roller may be cheaply and expeditiously constructed in an ordinary screw-lathe working automatically, as will be perceived, greatly lessening the cost of the machine. I is a plain roller mounted upon a shaft, K, having bearings at each end in the standards A. Said shaft is capable of a longitudinal movement in its bear-- ings, carrying the roller I with it, for the purpose to be presently explained. Below said roller I arrange one or more short rollers, L, each mounted upon a shaft, M, having bearings in short standards N N attached to the bed or base of the apparatus, and capable of beingraised or lowered by means of suitable setscrews. These rollers revolve in contact with the roller I, and are for the purpose of preventing s aid roller or the metal roller from springing or swagging during the operation of marking, scoring, or ribbing the cloth. 0 is a screw passing through the cross-piece C, and working in a collar attached to a frame, E, by means of which said frame may be elevated or depressed, for the purpose of inserting the cloth between the rollers, and to bring the desired amount of pressure upon the same, though other devices besides the screw maybe employed. At a short distance in front of the rollers F-and I, and parallel with the same, I

arrange a roller, P, for the purpose of supportv ing the cloth. This roller is mounted on a shaft, R, having bearings in the standards S S, secured to the base or bed of the machine, and is on, or nearly on, a level with the top of the roller I.

The operation of my apparatus is as follows: The oil-cloth, after having been properly prepared with the various coats,is passed between the rollers with the brush-coat uppermost. This brush-coat must be dried to such an extent before the cloth is subjected to the action of the machine that it will not stick or adhere to the scoring-roller in passing under it, but must be sufliciently soft to readily take the marks or impressions of said scoring-roller.
